SYSTEM THEORY OF OPERATION
(see Figure 2)
A CO
cylinder delivers carbon dioxide gas (CO
) to primary CO
regulator assembly which deliver regulated

2
CO
gas to adjustable secondary CO
regulators. Secondary CO
regulators delivers regulated CO
gas to the

carbonated water tank inside the Cooling Unit and also to the soft drink tanks. Plain water enters the Cooling
Unit and is pumped through and is pre-cooled by the refrigerated Hydro Boostâ coil. Cooled water continues
through the plain water cooling coils and into the carbonated water tank. Cold plain water entering the
carbonated water tank is carbonated by regulated CO
gas pressure also entering the tank. Carbonated water
2
leaves the carbonated water tank and enters the inlet side of the carbonated water circulating pump.
Carbonated water passes through the carbonated water circulating pump, through the carbonated water cooling
coil, and exits the Cooling Unit through an insulated python to a turnaround inside the dispensing station.
Carbonated water returns to the Cooling Unit by passing through the insulated python, through the Cooling Unit
carbonated water cooling coils, through the carbonated water tank which makes up the carbonated water
circulating system. As carbonated water is being dispensed from the dispensing station, carbonated water
circulating system is continuously being replenished from the carbonated water tank.
Plain water enters through the Cooling Unit two plain water inlet lines, through the plain water cooling coils, and
exists the Cooling Unit out through insulated python to the dispensing station. Regulated CO
gas pressure
2
exerted upon the soft drinks contents forces syrup from tanks, through Cooling Unit syrup inlet lines, through
syrup cooling coils, and exists the Cooling Unit out through an insulated python to the dispensing station.
The Cooling Unit refrigeration system is cooled by a Remote Condenser Coil and Fan Assembly (P/N
309602000) that is authorized by IMI Cornelius Inc. Use of any other Remote Condenser Coil and Fan
Assembly must be authorized by IMI Cornelius Inc. Use of an unauthorized Remote Condenser Coil and Fan
Assembly will automatically void the Cooling Unit factory warranty.
